293/12 is 24 and a lot of numbers. I think it is 24.4166667.
Answer:
7x + 15x= 21x
Step-by-step explanation:
7x + 15x
= (7 + 15)x
= 22x
The rate at which the sound travels in km/hr is 0.142km/hr
<h3>Conversion of m/s to km/hr</h3>
If a sound wave travels with a speed of 5120m/s, in order to convert to km/he, we will use the conversion factor below;
1hr = 3600secs
1km = 1000m
Using the conversion factor in our dimensional analysis
5120m/s = 5120m/1s * 1km/1000m * 3600s/1hr
5120m/s = 5120m/3600000
5120m/s = 0.142km/hr
Hence the rate at which the sound travels in km/hr is 0.142km/hr

#SPJ1
Answer:
18%
Step-by-step explanation:
= 
----> cross multiply
504(100) = 2800x
50400 = 2800x
= 
18 = x
Commission Rate: 18%
Since we are decreasing by 40%
The new value would be 100% - 40% = 60% of the value
New value = 60% of 800
= (60 / 100) * 800 = 480
Am giving you 480 as the answer.
